The Feb built '70 SS 454 car I bought in '73 had 2 different size hex head bolts on the side terminals. So that car would have come with the optional battery ? Had a huge tray too. I bought a new design, high output 1,000 amp battery from Sears in about '79 that was 12" long and it fit the tray. Too bad the batteries became famous for exploding as mine did...
